SUBHEATED COKE OLEN WITH VERTICAL HEATING FL'UES.

.npplicationiled July 13,

To ZZ whom. 'it may concer/1t.'

Be it known that I, WAL'rHnR HIBY, a-subject of the German Republic, residing at lNoordwijk aan Zee, the Netherlands, have in- 5 vented certain new and useful Improvements in Subheated Coke Ovens with Vertical Heating Flues (for which I have applied `tor a patent in Germany January 3, 1916 of which the following is a specification.

The easy accessibility and the very convenient manner ot regulation of the gas-` burners of the so-called sibheated ovens from the passages underneath the ovens has l5 been the main reason foi-the wide adoption of this kind ofan oven, but up to new the exact regulationr of the ail",` necessary i'o/r each burner, was not possible or very dih cultI and incomplete. By the present' invention thisfanlt has been avoided in the following manner:

Between theXoors of the ovens and the ceiling or' the subways an individual-airchaniber for each single burner has been arranged, the openings of which for the admission of the air can also be regulated from the passage ways underneath the ovens; the outlets of each individual gas` burner and of the corresponding air chain.- ber connect at thelower end of the corresponding vertical heating flue. The invention is represented on the drawing in connection with a coke oven with a double row of heating lues, and two heating lues' with two burners and two checker-workcharnbers are connected at the upper end of the heating lues and formi aclosed heat.- ing-system.; The constructijon is shown in Figures l, 2, 3, 4C and 5.

Between theovenchambers a, are the ver- 1920. serialino. 396,006.

the directionlof the draught is ythe same in the two adjoining chambers underneath each oven. The ovens, including the oven chambers and preheating devices, are raised so as to provide subways beneath them from which to regulate the valves. ln the form of the invention illustrated the ovens are carried on posts pj The heating lues between two adjacent oven chambers and the checlerworkl regenerators for preheating the air supplied to the lines and for receiving the. @vaste heat therefrom are A division wall '62 separates the dues. A'

Each

arranged in pairs.

wall d2 separates the regenerators. pair of flues and regenerators forms aheating unit, supplied with al regulatable amount of air and gas, the valves for regulating being manipulated from the subways beneath the oven structure. The adjoining regenerators which liel beneath each oven' chamber are also separated from each other by `a wall da. Aseries of units or pairs of flues and regenerators is thus provided running lengthwise of the oven chamber, each heating unit 0r pair being separated from the adjacent unit. The walls ba'gseparate the lines and the Walls g3 and the "briclrwork separate the regenerators. The regenerators and fines of each unit are completely enclosed These units forni a -selries of separate, independent, vself-contained heating systems arranged in rows along `each oven chamber. By alternately starting and reversing the draught, the dow of 'heating gases through each unit will be reversed.

All the cheoker-worli-chambers a? of one row connect with an underlying iue e through openings f, and all'the chambers' flues e and e1 the pipe connections i and il' to -the chimney-Hue VZ and from there intothe open air. lin the pipe connections z' and il are flap-valves ic and icl, which are alsol periodically opened and closed.

The draught in the fines and chambers is reversed from time to time and the working'is carried on. in the following manner: ln one case the heating gases pass through tuyere or burner passage c and the air for combustion through the openings It, the sole-fines e, the checker-work-chambers cl to the heating-fines b; in these heating-fines the combustion takes place in a vertical direction. The waste-gases travel downwards through heating-fines b1, checker-Workchambers d1, sole-fines el, pipe connections il and pass the opened Hap-valves .761 to the chimney flue Z and to the chimney; the Hap-valves h1 and le are closed.

About every half hour7 the draught-di.- rection is reversed and now the heatinggases enter enterthrough tuyere or burner passage c1, the air through opening la, sole fines el, checker-work-chambers all, to the heating-fines 61;. the waste-gases travel downwards through lues chambers (l, sole-dues e, pipe connections i, pass the opened Hap-valves k' and go through the chimney-flue Z to the chimney,'while theiiapvalves h and if, are closed.

The importance of the invention consists lchiefly inthe arrangement that for each individual heating-flue gas and air can be regulated in 'a remarkable Asimple manner from the substructure underneath the oven andthat consequently a uniform heating of the whole length or' the oven wall is ensured with absolute certainty. Both gas and air Iare regulated in a practically cold state, so that all the regulatii'ig arrangements may be easily handled and kept in goed order. Having now `described my invention, what l claim as new is: l

Lln `a horizontal colite oven with vertical l'ieating'lues7 said oven being raised and provided with subways underneath the joven to permit the operation of ther-egulating devices, the combination. of a pluralityof tuyeres for the introduction of the 'heating arranged in rows beneath the heating fines, and a row of separated re- 1 generator chambers for the preheating of the air, means for supplying air to said row `ot' regenerator chambers, one air regenerator chamber by the side or each tuyere, both the tuyeres and the air regenerator`cham bers being situated in the space between the Hc'ors ot the ovens and the ceilings of the Zin 'a 'horizontal coke `oven with vertlcal heating lues, said oven being raised :and provided witbsubways underneath the ranged in rows underneath the heating fines, a row of separated, checkerwork regenerators for preheating the air, one air regenerator by the side of each tuyere, a Hue underneath each row of checkerwork air regenerators, means lfor supplying air to said row ot regenerators comprising connections between said flue and each regenerator, a valve controlling each of said fines, the tiiyeres and the air regenerators being situated in the space between the floors of the oven and the ceilings of the subways.
